An audit of survival in small cell lung cancer

Abstract

A total of 351 previously untreated patients presented to this department with limited small cell bronchogenic carcinoma between 1974 and 1985. They were treated with either radical or palliative radiotherapy (152), chemotherapy alone (63), or combined chemoradiotherapy (136). Their 5-year survival rates were 2.6%, 0%, and 5.1% with median survival being 25.7, 29.0 and 47.4 weeks, respectively. Forty-seven patients were given radical radiotherapy, 30 of these received chemotherapy as initial treatment (20), as adjuvant (3) or at relapse (7). Their 5-year survival rate was 12.8%, with a median of 58 weeks, compared with 2.1% and 31.5 weeks for 241 patients who had palliative radiotherapy ( P<0.001). Seventeen of the 47 patients (36%) and 135 of the 241 patients (56%) were given radiotherapy alone. Univariate analysis showed that gender and age had no significant influence on survival but lymph node status did. The median survival for patients who had no lymph node metastases was 37 weeks compared with 24.5 for those who had ( P<0.01). The median and long-term survival rates for patients in this report contradict previous reports that radiotherapy has no influence on survival. Only patients who received radiotherapy, either alone, or with chemotherapy, have survived 5 years.
